ILLUMINATED WRITING IMPLEMENT.

This invention relates to attachments for pens, pencils and the like anobject being to provide means whereby an electric lamp may be removablyattached to a writing implement whereby the latter may be convenientlyused in dark places.

Another object of the invention is the provision of means whereby anelectric lamp may be attached to a writing implement so as to projectits rays of light to the point of the implement and at the same timeshield the eyes of the user.

Another object of the invention is the provision of an electric lampattachment for writing implements having novel and con venient means forcontrolling a circuit through the lamp.

lVith the above and other objects in view, the invention furtherincludes the following novel features and details of construction to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation of a pencil with the inventionapplied.

Figure 2 is an enlarged longitudinal sectional view of the invention perse.

Figure 3 is an enlarged section on the line 3-3 of Figure 2.

Figure 1 is a similar view on the line 1-4 of Figure 2.

Referring to the drawingsin detail wherein like characters of referencedenote corresponding parts it may be here stated. that while theinvention is shown as applied to a pencil indicated at 10, it may beattached to a pen, a firearm, or to various other implements or devices.

As shown in the drawing the invention comprises a tubular casing 11which is open at one end and this open end is beveled so that anelectric light bulb 12 may be carried within the casing suflicientlyclose to the outer end of the latter to provide a maximum amount oflight at the point of the pencil and at the same time shield the eyes ofthe USE-1'.

Serial No. 83,629.

18, while connected to the other terminal of the socket is a conductor19 having a conductor wire 20 attached thereto. The conductor wires 18and 20 are adapted to lead to a suitable .source of current, such as asmall dry cell capable of being carried in the pocket of the user.

The conductor 19 is interrupted so as to provide a space or gap 21 whichis adapted to be bridged by spring contact arms 22 which are secured toand extend in opposite directions from an insulating block 23. Thisblock 23 is slidable transversely of the cylinder 13 and has extendingfrom opposite sides buttons 24; which project through openings providedin the casing 11. The block may be moved transversely of the conductor19.

By reference to Figures 2 and 3 of the drawings it will be seen that bymoving the block transversely the .spring contact fingers may be engagedwith the adjacent ends of the conductor 19 so as to bridge the space orgap provided in the latter and complete a circuit through the lamp 12.When the block 23 is in the position shown in Figure 3 of the drawings,circuit through the lamp will be interrupted.

The conductors 17 and 19 are secured in place by means of pins 25. whilea pin 26 holds the spring contact fingers 22 to the block 23.

The conductors 17 and 19 carryat their outer ends clips 27 forconnection with the conductor wires 18 and 20.

Extending from the casing 11 are spaced pairs of oppositely extendingcurved gripping fingers 28 which are adapted to engage around the pencil10 to hold the device in place.

The invention is susceptible of various changes in its form, proportionsand minor details ofconstruction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having descriped the invention what'is claimed is A device of the classdescribed comprising a tubular casing open at one end, a socketedinsulating cylinder within one end. of the casing, a lamp socket withinsaid cylinder, an electric lamp within the socket, means including aninterrupted conductor whereby the current may be supplied to the lamp,an insulating switch block movable transversely of the interruptedconductor, oppositely extending spring contact fingers carried by theblock, means whereby the block may be moved to move the contact fingersinto and out of contact with the interl'uptecl conductor for controllingthe How of current through the latter and means whereby the device maybe rei'novably se- 10 cured in position for use.

In testimony whereof I affix my signature.

THOMAS J. BROOKS.
